>>6770368Reverse shading? Wtf is that? You mean pre-shading?
But seriously the best kind of shading i found is highlighting(now that I wrote it it sounds like mumbo-jumbo).
Basically you paint a whole part black/grey and apply proper colours via airbrush to the center of the parts, less on the edges so base coat shows up a bit.
Easy and with awesome results(model: Pg Exia by Inkedfatboy from reddit)
